Is Alpha Still Invite Only? I'm Able to Select Alpha But Was Never Invited?

There is only a limited number of free slots in Alpha/Alpha Skip Ahead.

If someone in Alpha/Alpha Skip Ahead leaves, or is removed due to inactivity, participants in Beta are invited to Alpha. However, Beta participant invitations are sent out to those, that leave valuable feedback, find bugs, and are most active in the beta
group.

So it's not how long you are in the program, but how valuable your input and bug reporting was in the past.

Added to the fact that invitations are only sent out if there is new room in Alpha, you might have to wait a while to get invited. Just provide good feedback and be patient.

Still waiting to be invited to Alpha..

To be a alpha member you need to provide quality reports and they might invite you but at this stage they are not inviting new alpha members as the alpha ring is full but usually every 6 months they invite new members to alpha so the best way is to wait
and submit reports

Hello,

i am from Germany ....

Now i want to join Alpha Ring, but Microsoft Support tells me, the only way i can join Alpha Ring ist via Invite from another People in the Alpha Ring.

But i dont know anyone in Alpha Ring.

What can i do to join Alpha Ring in XBOX Insider Hub?

Greetings from Germany as well.

Previously, before there were rings, you had to be invited by someone already in the "Xbox Preview Program" as it was called back then.

This was then changed to the Xbox Insider Program, and anyone was able to join by installing the Xbox Insider App, and anyone is allowed to choose a ring up to Beta.

Alpha and Alpha Skip Ahead are only available by invitation from someone at Microsoft, and only if new free slots are available.

You will have to "earn" the privilege to be considered by providing regular and quality feedback, and hope that there are Alpha/Skip Ahead members that provided less feedback, and are removed from the Alpha/Skip Ahead rings.

So the only thing we can suggest is to be patient, and to continue participating in the available activities, and wait for the invitation.

You don't unless you join the insiders program which is on alpha skip and alpha only

Which both are invite only
